A dedicated power cable is required to connect 3-phase mains supply and ship’s ground to
the hoisting motor on the hull unit. The connections are made to the Motor Control Unit.
The cable must be provided by the installation shipyard.
Terminal block
E301
is located at the bottom of
the Motor Control Unit. The three AC mains
power cables, as well as ground, are connected
from the ship’s circuit breakers to
E301
. The
cable screen on the power cable must be
grounded in the cable gland.

The physical connections to the motor are
made inside the terminal box on the motor.
To avoid serious damage to the hoisting motor,

you must verify that the electrical connections
are made in accordance with the supplied
3-phase AC voltage. Observe the difference
